"Very responsive to come out ainitially and access damage and get fixed as all was paid for by insurance. They also agreed to installing a skylight where the tree came thru (there was not a skylight before). It was installed well and has never leaked. That's all the good news I have folks. HOWEVER we had 'total replacement to original status' insurance coverage and first go around all they were going to do was patch damaged areas of roof. matching tiles "as best they can". After much bickering back and forth, they finally replaced entire roof. 3 times. yes, three times as the first 2 times work was substandard- and eaked. They did not overlap roof tiles and did not flash properly. When insurance overseer finally agreed to redo entire roof to "original" with a 30 year guarantee, she was subsequently fired by the insurance company after the job was done. Inside the house, the subcontractor they hired to fix our wall and ceiling was horrendous. "Johnny" from Mississippi put up a wall that was not linear -nit bowed. He said our house was crooked and he could not fix that. There was a good 2 feet crawl space between inside wall and outside house. We insisted he redo it (multiple times.) till he got it straight, finally, He said "the wife" was being too fussy. Then he replaced smooth ceiling with a popcorn ceiling because he said he couldn't fix the drywall plaster lines...now we have the task of taking off the popcorn, replacing the drywall ceiling, and replastering correctly. . We grew weary of him and decided not to have him redo. As for coming "on time", well, we learned that "on time" is a relative term...seems to mean just showing up sometime in the morning. Bottom line: Don't let your insurance company bully you into using this company and certainly do NOT hire them on your own."

We are a Licensed & Bonded Public Claims Adjusting Firm headquartered and founded in Tampa Bay, Florida. We represent clients in Florida, Georgia & Virginia. Our goal is to make sure that our clients receive ALL the money that they deserve from the insurance carrier. Our firm will communicate with the insurance company and act as an advocate for the policyholder during the claims process. We prepare a full scope and itemized estimate of damage for residential or commercial properties. We review the insurance policy for coverage and explain the claims process, as well as duties after a loss, and what to expect from the insurance carrier throughout the process of the claim.

"Reliable Claims Adjusting provided invaluable assistance, ensuring that our insurance provider paid an appropriate amount based on our policy and the loss we had experienced. When we first filed our claim with the insurance company they tried to deny it completely, which was really frightening. Andrew with Reliable Claims Adjusting explained the whole process of working with a public adjuster, and ultimately was able to secure funds that should cover all of our needed repairs. We are incredibly grateful!"

Radon gas testings FAQs

Radon gas is a serious health hazard, as it is the second leading cause of lung cancer in the United States. When inhaled, radon breaks down into radioactive particles that can damage lung tissue. Because radon is odorless and invisible, regular testing every two years is crucial to detect its presence. If you have recently remodeled or started using different areas of your home, like the basement, additional testing is essential to ensure your family's safety.

Yes, you need a radon test to ensure your home is safe. The EPA recommends testing your home for radon every two years and after any renovations. Since about one in every 15 homes has elevated radon levels, regular testing is essential. Including a radon test in your home inspection is crucial when buying or selling a property, and some areas require disclosure of radon levels by law. Don't rely on neighboring homes or regional data; the only way to know your home's radon levels is through testing.

Certified professionals conduct radon testing, including accredited home inspectors and specialized radon mitigation companies. These experts follow strict EPA guidelines and use calibrated instruments to accurately measure radon levels throughout your home. Choosing a certified provider ensures you receive reliable results that protect your family's health and property.Professional testing is crucial for accurate detection and effective mitigation if needed.

Radon inspectors typically specialize in testing and assessing radon levels but may not perform mitigation services themselves. If your radon inspector identifies elevated levels of radon in your home, they will recommend a qualified radon mitigation specialist to address the issue. These mitigation experts install systems designed to reduce radon concentrations effectively, ensuring your home is safe.

No, air purifiers are not effective in removing radon gas from your home. Air purifiers are designed to filter out particles like dust and pollen, but radon is a radioactive gas that cannot be captured by standard air filters. To reduce radon levels, you need a specialized radon mitigation system that removes the gas from your home, ensuring your indoor air remains safe.

While opening windows may temporarily reduce radon levels by allowing some gas to escape, it is not an effective long-term solution. Radon continuously enters your home from the soil, and relying on open windows is not practical or sufficient to reduce levels significantly. To effectively lower radon concentrations, you need a professional radon mitigation system that actively removes the gas, ensuring consistent and safe indoor air quality.
